I still don’t understand how you can “push the button” on a bike without trying/riding a few first?
Right from the beginning of serious “cycling” I learned from test riding at a good dealer a Specialised Hardrock, Rockhopper, Rockhopper aluminium, and then an Marin of some description, being a bit “meh” on them all, then buying a well underspecc’ed and more expensive Orange Clockwork. Seriously, the bike I bought had just Alivio, and was 25% more than the others, but it absolutely sang to me as a bike, rather than just a “conveyance”.
The Giant might be a splendid bike, but only for those who it fits well. Your ideal bike might actually not be that bike, it might be mroe, or less, and better or lower spec. Its about the best fit for you, not VFM.
Especially important on Road bikes. If you got £750 to spend on a second push bike, you probably have £850 to spend at a LBS, having tried a few bikes and thus working out why they are more expensive than the interweb. Its a bike, not a bloody hoover.
